“Hillary Clinton did not know how to use a computer to read and send emails when she entered office as the nation’s top diplomat in 2009.

She only knew how to read her messages via BlackBerry, according to an official at the time.

Clinton’s chief of staff, Cheryl Mills, told State Department official Lewis Lukens that there could be a “problem,” because Clinton “does not know how to use a computer to do email — only [Blackberry],” he wrote in a 2009 email released on Monday.”
